I accidentally ordered the 24v instead of the 12v fan for my e3dv6 when i ordered the fan shroud. Does anyone know the cfm requirements? I happen to have a 12v 1030 laying around but it has such low airflow…

You should be able to exchange it, heck I’m happy to do so even if you didn’t buy from Filastruder.

But to answer your question: at least 4CFM.

@Tim_Elmore , doh looks like this one is 3.3. Maybe the better duct will be enough to get me up and running again.

With a V6 the fan is crucial to getting good results, particularly with low temp plastics. While it doesn’t sound like much, 1 CFM is about a 25% reduction. Tim is in a better position to comment than I am but I would use exactly what is speced in a stock V6 kit. It’s a great part but can be tweaky at times to get up and going if all is not right.

@dstevens_lv that’s what people keep telling me.

I was hoping with some over-extrusion the 3.3 cfm fan would be good enough for some mediocre prints. It was not. The layer got thinner as it progressed which makes sense. OTOH, I did verify that my new inductive sensor and auto-“leveling” works.

I’ll throw one of these into my next amazon order. http://www.amazon.com/Yeah-Racing-Tornado-Cooling-YA-0180BU/dp/B00S7P9AUQ/

That one you linked is 5 volts, not 12. It’s also more expensive than an E3D fan?

Ok, I have a 5.1 cfm fan pointed towards the e3dv6 (is this the right direction?) with the blue molded shroud. There is no significant improvement. Thoughts?
